- The wing structure consists of spar caps made of carbon fiber rovings and carbon skins, glass fiber fabric and fitted with full span flaperons made by the same composites. The wings are connected with a tongue arrangement, secured
with two main pins. All control surface hinge gaps are sealed with Mylar strips and Teflon-coated tape

- The landing gear consists of a 6 inch electrically operated retractable main gear, steerable tail wheel and small wheels at both wing ends

This aircraft is certified in the ULN category. The following simple maneuvers are anyhow permitted:

- Lazy Eight

- Chandelle

- Steep turns

- Stall turns

The stall speed with Airbrakes retracted and CG in the mid to rear position:

Gross weight 300 kg

Flap Position Stall Speed (IAS)

+3 61 km/h

+2 64 km/h

+1 67 km/h

0 70 km/h

The stall speed in all flap settings is increased by approximately 3 km/h with the airbrakes extended. The landing gear position has no measurable influence on the stall speeds. Optimum- economical climb: At safe altitude reduce engine
power to 3800-4000 RPM for max altitude gain in one step (cca 1100 m) until completely batteries drain. The Albastar AS-15M has very good cross wind handling characteristic due to »V« wing shape allowing high bank angles during touch
down. The maximum demonstrated crosswind components are:
